The Effect of Differential Settlement of Supports on a Large Steel-Framed Boiler Supporting Structure [ ]

The paper gives details of the distribution of forces induced in the members and variation of steel weight of an existing Boiler supporting structure, due solely to a vertical settlement of any column. The construction is described and typical frames were chosen and analyzed elastically. From this approach, a pattern appears to emerge, and it is hoped that this information will be of use to engineers engaged in the design of such structures on difficult sites where sizeable differential settlements may have to be accepted.
